[0008] Optionally, in some embodiments, the light box 3 includes a first housing 30 and a second housing 36. The first housing 30 is fixedly connected to one end of the snap-fit ​​plate 27. The first housing 30 has a first cavity 31 and a first side wall 33 and a first bottom wall 32 surrounding the first cavity 31. The first bottom wall 32 has an illumination groove 39, and a lampshade is installed on the surface of the illumination groove 39. The end of the first side wall 33 away from the first bottom wall 32 is a first end 396, and the first end 396 is located around the first housing 30. The first housing 36 has a groove 38 and a second housing 34 that mates with the first housing cavity 31. It also has a second side wall 395 and a second bottom wall 394 surrounding the second housing cavity 34. The end of the second side wall 395 away from the second bottom wall 394 is a second end 392. The second end 392 is provided with a protrusion structure 37 that mates with the groove 38. The second housing 36 is mounted on the first housing 30 through the groove 38 and the protrusion structure 37.

[0010] The technical solution provided in this application may include the following beneficial effects:

[0011] This application provides an intelligent lighting device for open-pit coal mining faces. When the lighting amplitude needs to be adjusted during mining operations, the motor is started. The motor drives the first gear to rotate, and the first gear drives the second gear to move intermittently. The motor is a servo motor. The second gear drives the rotating shaft to rotate intermittently. One end of the rotating shaft is movably connected to one end of the support column. The rotating shaft drives the light box connected to the mounting frame to move intermittently, thereby enabling the lighting components inside the light box to be flexibly adjusted, thus facilitating lighting for workers during mining operations and improving work efficiency.

[0012] This application achieves a sealing effect between structures by using a protruding structure in conjunction with a groove on the first housing. This not only avoids various sealing failures associated with conventional sealants, significantly reducing the failure rate, but also eliminates the need for deliberate or precise control of the amount of sealant used between housings or surface treatment after excessive application. While providing a strong sealing effect, assembly is simpler and more convenient, saving manufacturing time and reducing manufacturing costs. Furthermore, the protruding structure squeezed out of the groove also provides an auxiliary sealing effect on the outer perimeter of the groove, further enhancing the waterproof sealing of the lightbox housing. This prevents water from entering the lightbox during rainy weather, protecting the internal structure and extending the lifespan of the lighting device.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] To address the aforementioned issues, this application provides an intelligent lighting device for open-pit coal mining faces, which enables flexible adjustment of the lighting components inside the light box, thereby facilitating lighting for workers during mining operations and improving work efficiency.

[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] See Figure 1 The intelligent lighting device for the open-pit coal mining face includes a base plate 4, a support column 1 fixedly connected to the surface of the base plate 4, an adjustment mechanism 2 installed on the top of the support column 1, and a lighting mechanism installed on the adjustment mechanism 2.

[0029] See Figure 2 The adjustment mechanism 2 includes a mounting frame 20, which is fixedly connected to the top of the support column 1. A motor 21 is fixedly connected inside the mounting frame 20. A first gear 22 is fixedly connected to the output end of the motor 21. A second gear 23 is meshed with one side of the first gear 22. A rotating shaft 28 is fixedly connected to the inner surface of the second gear 23. The rotating shaft 28 is rotatably connected inside the mounting frame 20. A sealing sleeve 24 is sleeved on the surface of the rotating shaft 28. The sealing sleeve 24 is located outside the mounting frame 20. A connecting block 25 is fixedly connected to one end of the rotating shaft 28. A snap-fit ​​plate 27 is snapped onto the surface of the connecting block 25. A fixing bolt 26 is threaded through the snap-fit ​​plate 27 and the surface of the connecting block 25. A lighting mechanism is fixedly connected to one end of the snap-fit ​​plate 27.

[0030] Specifically, when adjusting the lighting amplitude during mining operations, motor 21 is started. Motor 21 drives the first gear 22 to rotate, and the first gear 22 drives the second gear 23 to move intermittently. Motor 21 is a servo motor. The second gear 23 drives the rotating shaft 28 to rotate intermittently. One end of the rotating shaft 28 is movably connected to one end of the support column 1. The rotating shaft 28 drives the lighting mechanism connected to the mounting frame to move intermittently, thereby enabling the lighting mechanism to flexibly adjust the lighting. When the lighting mechanism needs to be repaired, the maintenance personnel use tools to climb to the lighting mechanism and then rotate the fixing bolt 26. The fixing bolt 26 disengages from the snap plate 27 and the connecting block 25, causing the lighting mechanism to detach, thereby removing the lighting mechanism for inspection and maintenance. The model of motor 21 is ECM A–C1 06 02 ES.

[0031] See Figure 3 In some embodiments, the lighting mechanism includes a light box 3, a circuit board 5 is installed inside the light box 3, an LED tube board 6 is installed on one side of the circuit board 5, a diffuser 7 is installed on the lower side of the LED tube board 6, and a lighting groove 39 is provided at the bottom of the light box 3.

[0032] Specifically, the diffuser 7 is model BJQ5015. It provides power and controls the light source status through the circuit board 5. It is connected to the circuit board 5 through the LED tube board 6 for emitting light. The diffuser 7 can make the light more uniform. Both the LED tube board 6 and the diffuser 7 are existing devices.

[0033] See Figure 4-5In some embodiments, the light box 3 includes a first housing 30 and a second housing 36. The first housing 30 is fixedly connected to one end of the snap-fit ​​plate 27. The first housing 30 has a first cavity 31 and a first side wall 33 and a first bottom wall 32 surrounding the first cavity 31. The first bottom wall 32 has an illumination groove 39, and a lampshade is installed on the surface of the illumination groove 39. The end of the first side wall 33 away from the first bottom wall 32 is a first end 396, and the first end 396 has a groove 38 circumferentially arranged around the first housing 30. The second housing 36 has a second cavity 34 that cooperates with the first cavity 31 and a second side wall 395 and a second bottom wall 394 surrounding the second cavity 34. The end of the second side wall 395 away from the second bottom wall 394 is a second end 392, and the second end 392 has a protrusion structure 37 that cooperates with the groove 38. The second housing 36 is installed on the first housing 30 through the groove 38 and the protrusion structure 37. The lighting mechanism is installed in the first cavity 31 and the second cavity 34. The second housing 36 is composed of a rigid part 393 and a soft part 35. The soft part 35 surrounds the outer wall of the rigid part 393, and the protrusion structure 37 is a soft part integrally formed with the soft part 35. The protrusion structure 37 is press-fitted with the groove 38. The rigid part 393 has a step 391 at the second end 392 near the outer side, and the soft part 35 is fitted with the step 391.

[0034] Specifically, the cooperation between the protruding structure 37 and the groove 38 on the first housing 30 achieves a sealing effect between the structures. This not only avoids various sealing failures associated with conventional sealants, significantly reducing the failure rate, but also simplifies assembly while maintaining a strong sealing effect, saving manufacturing time and reducing manufacturing costs. The protruding structure 37 and the groove 38 are interference-fitted in the depth direction of the groove 38 and clearance-fitted in the width direction, where the width direction is perpendicular to the depth direction. During the assembly of the first housing 30 and the second housing 36, due to the soft nature of the protruding structure 37, it is compressed within the groove 38 and gradually diffuses outwards, allowing the first housing 30 and the second housing 36 to assemble well. Simultaneously, the portion of the protruding structure 37 compressed within the groove 38 also provides auxiliary sealing around the groove 38, further enhancing the waterproof sealing of the light box 3's waterproof housing.

[0035] The raised structure 37 and the soft part 35 also have good structural stability and strength. With the rigid part 393 providing a certain support strength, the waterproof sealing performance of the light box 3 waterproof shell is even better. The rigid part 393 is located at the second end 392 and a step 391 is provided near the outer side to support the soft part 35. Through the avoidance effect of the step 391, the connection cross-sectional area between the raised structure 37 and the soft part 35 is larger, thereby having stronger connection strength and connection stability, ensuring the reliability of the waterproof sealing performance of the light box 3 waterproof shell.

[0036] The working process of this application:

[0037] When the lighting amplitude needs to be adjusted during mining operations, motor 21 is started. Motor 21 drives the first gear 22 to rotate, and the first gear 22 drives the second gear 23 to move intermittently. Motor 21 is a servo motor. The second gear 23 drives the rotating shaft 28 to rotate intermittently. One end of the rotating shaft 28 is movably connected to one end of the support column 1. The rotating shaft 28 drives the light box 3 connected to the mounting frame to move intermittently, thereby driving the lighting components inside the light box 3 to flexibly adjust the lighting.

[0038] When maintenance is required on the lighting components inside the light box 3, the maintenance personnel use tools to climb to the light box 3 and then rotate the fixing bolt 26. The fixing bolt 26 disengages from the snap plate 27 and the connecting block 25, causing the light box 3 to detach and be removed for inspection. The cooperation between the protruding structure 37 and the groove 38 on the first housing 30 achieves a sealing effect between the structures. This not only avoids various sealing failures associated with conventional sealant sealing, significantly reducing the failure rate, but also eliminates the need for deliberate or precise control of the amount of sealant used between the housings or surface treatment after excessive application. In addition to a strong sealing effect, assembly is simpler and more convenient, saving manufacturing time and reducing manufacturing costs. The protruding structure 37 and the groove 38 are interference-fitted in the depth direction of the groove 38 and clearance-fitted in the width direction of the groove 38, where the width direction is perpendicular to the depth direction.

[0039] In this way, during the assembly of the first housing 30 and the second housing 36, based on the soft nature of the protruding structure 37, the protruding structure 37 is squeezed within the groove 38 and gradually diffuses automatically to the surrounding area, i.e., the periphery of the groove 38, so that the first housing 30 and the second housing 36 can be well connected and assembled. At the same time, the part of the protruding structure 37 squeezed out within the groove 38 can also play an auxiliary sealing role on the periphery of the groove 38, thereby further improving the waterproof sealing of the light box 3 waterproof housing. The protruding structure 37 and the soft part 35 also have good structural stability and structural strength. With the hard part 393 providing a certain support strength, the waterproof sealing performance of the light box 3 waterproof housing is even better.

[0040] The rigid part 393 is located at the second end 392 and a step 391 is provided near the outer side. It is configured to support the soft part 35. Through the avoidance effect of the step 391, the connection cross-sectional area between the protruding structure 37 and the soft part 35 is larger, thereby having stronger connection strength and connection stability, and ensuring the reliability of the waterproof sealing performance of the waterproof housing of the light box 3.
